It features advanced power monitoring capabilities suitable for complex power networks, multiple communication interfaces, and support for remote monitoring and data analysis.

[0091] The remote control center generates control instructions for each device in the pumping station based on the received data, and sends them to the main controller through the Internet and wireless transmission module. The main controller sends the control instructions directly or through general control to the corresponding equipment in the pumping station.

[0092] In the above process, the master controller and general controller are only used for data transmission and do not involve the generation of instructions. All control instructions are generated in the remote control center.

[0093] It should be noted that the process of the remote control center generating control instructions is not the technical solution claimed by this utility model. The technical solution claimed by this application is only the connection of various hardware devices and the transmission of status data and control instructions between sensors, controllers and the remote control center.

[0094] The master controller and general controller are only used to receive and transmit data collected by sensors and receive and send control instructions, and do not generate any control instructions.

[0095] It should also be noted that the pump station mentioned in the present invention is a prior art, and its shape, layout and use process are common knowledge in the field. That is, the ground sewage pump, main pump, valve, screen machine, water inlet and outlet, pool and smart meter mentioned in the present invention, etc., are all known to those skilled in the art in terms of their shape and the connection method of the surrounding equipment, so there is no need for further explanation in the drawings of the specification. For example, the urban sewage pump station in Fuyang City is an unmanned pump station, and the operator can monitor and control the on-site equipment in real time in the remote control center. Among them, the installation position, physical connection relationship and electrical connection relationship of each device in the pump station are all common knowledge in the field, and the setting position of each sensor is also common knowledge in the field. The sewage pump station can directly apply the present invention.

[0096] Among them, the ground sewage pump collects the operating status of the ground sewage pump through the ground sewage pump sensor and inputs the switch value into the main controller; the switch value of the operating status of the ground sewage pump is usually obtained through the following sensors:

[0097] 1. Travel switch (limit switch)

[0098] Start / Stop Status: A travel switch can be used to detect the mechanical state of a surface sewage pump, such as whether it is on (running) or off (stopped). Travel switches are typically installed at key locations on the pump. When the pump shaft or pump cover reaches a certain position, the switch triggers a signal, indicating the pump's status. Schneider Electric's XS series is commonly used.

[0099] 2. Current relay (overload relay)

[0100] Operating Status: A current relay detects whether the current flowing through the surface sump pump motor is within the normal range. A normal current indicates the pump is operating, while excessively high or low current may trigger a fault alarm (open = fault, closed = normal). The output of the current relay is typically a switching value, indicating the operating or fault status of the surface sump pump. Schneider Electric's LRD series is commonly used.

[0101] 3. Pressure switch

[0102] Operating Status: A pressure switch can be used to monitor the outlet or inlet pressure of a surface sewage pump. When the pressure reaches a set value, the switch triggers and provides a digital signal. For example, if the pressure is abnormal, the pressure switch will trigger an alarm (open = abnormal, closed = normal), indicating whether the pump is operating normally. Honeywell's WLD2 series is commonly used.

[0103] 4. Float switch

[0104] Liquid level control: Float switches are commonly used for liquid level control in surface sewage pumping stations. When the liquid level reaches a set height, the float switch triggers, starting or stopping the pump. The float switch's signal indicates whether the pump is running or stopping due to the liquid level change. The GROVE XKP series is commonly used.

[0105] 5. Temperature switch

[0106] Overheat protection: A temperature switch is used to detect the temperature of the surface sewage pump or motor. When the temperature exceeds the safe range, the temperature switch triggers a signal, indicating that the surface sewage pump is overheating, and provides a switching value for fault alarm. The Omron K7L series is commonly used.

[0107] 6. Vibration switch

[0108] Vibration monitoring: A vibration switch can be used to detect abnormal vibrations in surface sewage pumps. When the vibration exceeds a set threshold, the switch signal triggers an alarm, indicating whether the surface sewage pump is operating abnormally. SKF CM series sensors are commonly used.

[0109] 7. Main power switch

[0110] Power status: Monitors whether the power supply of the surface sewage pump is connected. The power switch can provide a simple switching signal to indicate the power status of the pump (on = power on, off = power off). Generally, Schneider Electric: NSX series can be used.

[0111] Specifically, the inlet pressure sensor is installed in the pump station's inlet pipe, near the pump station's suction port, to measure the pump station's inlet pressure. The outlet pressure sensor and outlet flow sensor are installed in the pump station's outlet pipe, near the pump station's discharge port, to measure the pump station's outlet pressure and flow, respectively. The inlet and outlet pressure sensors output a 4-20mA current signal to the master controller. These sensors are typically Honeywell PX2 or PX3 series. They provide high-precision pressure measurement suitable for liquid and gas pressure monitoring, providing a 4-20mA analog signal suitable for industrial automation and process control applications.

[0112] The outlet flow sensor can be an electromagnetic flowmeter, such as the Endress+Hauser Promag W400. It is suitable for high-precision measurement of sewage and industrial liquids and supports a 4-20mA signal output.

[0113] Specifically, the pool level sensors are installed in the pump station's inlet, pump, transfer, and drain pools to monitor the water levels within their respective pools. These sensors output a 4-20mA current signal to the master controller. These sensors can use the Endress+Hauser ultrasonic level sensor, model: Prosonic FMU90. These sensors are suitable for non-contact level measurement of various liquids, offer high accuracy and stability, and support a 4-20mA current signal output, facilitating integration with control systems.

[0114] Specifically, the valve sensor outputs the switching quantity to the main controller. In the pump station, the valve sensor is mainly used to collect the status switching quantity of the valve to ensure the correct operation of the valve and the normal operation of the system. The utility model uses a common valve sensor to monitor whether the valve is in an open or closed state, ensuring that the valve operates according to the preset state to prevent system failure or leakage. Generally, a switching quantity sensor Honeywell can be used: Model: WLD2 series (for float valves), which has high reliability and is suitable for various switch status monitoring. It is usually a switching quantity output (ON / OFF) and can be connected to a control system.

[0115] Specifically, the screen machine sensor outputs a switching value to the master controller. In the pumping station, the screen machine sensor is primarily used to monitor and control the operating status of the screen machine. The switching values ​​collected by the screen machine sensor primarily include: screen machine operating status, to monitor whether the screen machine is running (on or off), ensuring normal operation of the screen machine to treat solid matter in sewage; and screen machine blockage or fault status, to detect any blockage or fault (such as overload) in the screen machine, thereby promptly detecting and issuing an alarm for maintenance or treatment.

[0116] The Honeywell WLD2 series switch sensors in the grille machine sensors are suitable for monitoring various switch states, such as the operating status of the grille machine, providing switch outputs (ON / OFF) that can be connected to a control system. The Omron D4N series fault detection sensors in the grille machine sensors are used to detect mechanical equipment failures or abnormal conditions, providing switch outputs (ON / OFF) to indicate faults or blockages in the grille machine.

[0117] Specifically, the master controller receives control instructions sent by the remote control center and outputs switch quantities to the control input ends of the ground sewage pump, screen machine and valve.

[0118] Preferably, the master controller sends start and stop control instructions to the valves, screen machines and ground sewage pumps.

[0119] Specifically, the main controller receives the control instructions issued by the remote control center and forwards them to the general controller. The general controller outputs a 4-20mA current signal to the control input end of the main pump according to the control instructions to control the main pump frequency; the general controller outputs a switch value to the control input end of the main pump to start and stop the main pump.

[0120] In this specific embodiment, a universal controller controls the start and stop of main pumps 1, 2, and 3 in pumping stations. The number of main pumps can be adjusted based on site conditions. The universal controller can collect the operating status and frequency of the main pumps, and can also adjust the pump's water flow rate by modifying the frequency according to control instructions. The universal controller is connected to the master controller via the COM3 communication port. The master controller can control the gate switch, the start and stop of the surface sewage pump and the screen, and collect the operating status of the equipment. It collects data from smart meters via 4-20mA signals and connects to the smart meter via the COM2 communication port to read various power data from the meter, such as voltage, current, active power, reactive power, and power factor. The master controller is connected to the wireless transmission module via the COM1 port. The wireless transmission module is plugged into a 4G Telecom Internet of Things card, which transmits data from the master controller to the control center via the wireless network. The 4G Telecom Internet of Things card uses a dedicated line connection, which increases security and confidentiality while reducing service charges.

[0121] The sensors used in the present invention are all mature components in the prior art, and their usage, installation positions relative to the collected objects, and working principles are public common sense in the field.
